The US barrel that I bought had the gas port already drilled, along with the groove for the handguard retainer. My Polish barrel does not, which is one of the reasons why I started with the US barrel.
I have pinned everything except the FSB. I don't trust my eyes to tell me it is straight, so I may wait until I test fire it before pinning it.
The barrel was easier to drill than I expected. Went through it like butter.
